DETAILED DESCRIPTION

The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.
In the present disclosure, unless stated to the contrary, the used directional terms such as "up", "down", "front", "rear", "left", "right" may refer to the drawing directions of FIG. 1 and FIG. 4. An up-down direction may also refer to a gravity direction of the laundry treatment apparatus. The terms "inner" and "outer" refer to the inner and outer faces of the self-contour of each component. The terms "first" and "second" used are for distinguishing one element from another element, and have no sequence or importance. In addition, when the following description involves the accompanying drawings, the same reference numerals in different drawings represent the same or similar elements, which will not be repeated in the present disclosure.
According to some embodiments of the present disclosure, a laundry treatment apparatus is provided, which may be a double-drum washing machine, a double-drum dryer, a double-drum washing and drying integrated machine, and the like. Referring to FIG. 1 to FIG. 10, the laundry treatment apparatus includes: a cabinet 1; a first drum 2 disposed within the cabinet 1; a second drum 3 disposed within the cabinet 1, where the second drum 3 is positioned laterally above the first drum 2, that is, the second drum 3 is positioned laterally above the first drum 2; a vibration damping structure for the second drum 3 is disposed above the second drum 3.
The first drum 2 and the second drum 3 in the present disclosure may be, for example, the outer drum of a washing machine. The drum structure of a washing machine usually includes an outer drum and an inner drum located inside the outer drum. The clothes to be washed are placed in the inner drum, and the washing is completed under the rotation of the inner drum, while the outer drum remains stationary to support and fix the inner drum. The first drum 2 and the second drum 3 may have the same outer diameter or different outer diameters. For example, an outer diameter of the first drum 2 ranges from 500 mm to 575 mm, and an outer diameter of the second drum 3 ranges from 150 mm to 200 mm.
Different from a single-drum washing machine, the double-drum washing machine has a more complex structure due to the addition of one more drum and the vibration damping equipped for the added drum. For the needs of space avoidance and the like, a space is usually left between the second drum 3 and the inner wall of the cabinet 1. However, it is limited by the limited arrangement space, although a certain space is left above the second drum 3, the space is usually insufficient for arranging other components with a slightly larger volume. In addition, the vibration above the second drum 3 is mostly small-range vibration. Considering the above technical problems, in the laundry treatment apparatus provided by the present disclosure, a vibration damping structure 4 for the second drum 3 is disposed above the second drum 3, which can fully utilize the limited space above the second drum 3 while meeting the vibration damping requirement of the second drum 3. Thus, the laundry treatment apparatus of the present disclosure can arrange the vibration damping structure 4 reasonably. It should be noted that "above the second drum 3" refers to above a horizontal plane where a center of a drum mouth or a drum bottom of the second drum 3 is located. The center of the drum mouth refers to an intersection point of a central axis of the drum body and the plane where the drum mouth is located; for example, if the drum mouth is a circle, the center of the drum mouth is a corresponding circle center; the center of the drum bottom refers to the intersection point of the central axis of the drum and the drum bottom; for example, if the drum bottom is a circle, the center of the drum bottom is a corresponding circle center, or the center of the drum bottom may also be the intersection point of the drum bottom and a rotating shaft that drives the rotation of the drum body. "The vibration damping structure 4 for the second drum 3 is disposed above the second drum 3" means that the vibration damping structure 4 is at least partially located above the second drum 3, that is, the vibration damping structure 4 extends downward from a connection point with the second drum 3 or the cabinet 1 to above the second drum 3.
In some embodiments of the present disclosure, referring to FIG. 1 to FIG. 10, the diameter of the first drum 2 may be larger than that of the second drum 3. In this way, the first drum 2 may be used for washing clothes with a larger volume or heavier weight, and the second drum 3 may be used for washing clothes with a smaller volume or lighter weight.
In some embodiments, referring to FIG. 1 to FIG. 10, the vibration damping structure 4 may be disposed only above the second drum 3. In other words, in some embodiments, except that the vibration damping structure 4 is disposed above the second drum 3, no other structures are disposed at other positions of the second drum 3, which is beneficial to further save space; alternatively, a balancing member to be introduced later or other devices different from the vibration damping structure 4 may also be disposed at other positions of the second drum 3, which will not be described in detail here.
It should be noted that the present disclosure is not intended to limit the specific form of the vibration damping structure 4, and any structure that may be connected above the second drum 3 and may suppress the vibration of the second drum 3 can be applied to the present disclosure.
In some embodiments of the present disclosure, referring to FIG. 1, the vibration damping structure 4 may include a first buffer member 41, and the first buffer member 41 may be connected with the top plate 11 of the cabinet 1. The first buffer member 41 may be, for example, an elastic structure such as a suspension spring, or a damping structure such as a damper. When the first buffer member 41 is a damper, it can not only provide a vibration damping effect, but also play a role in supporting the second drum 3. Here, since the vibration damping structure 4 is disposed above the second drum 3, the vibration damping structure 4 is relatively close to the top plate 11 of the cabinet 1. In this way, the connection between the vibration damping structure 4 and the cabinet 1 can be simply realized by using the top plate 11. Here, the first buffer member 41 may be directly connected to the top plate 11, so that the top plate 11 may be configured to absorb the vibration of the second drum 3. For the consideration of lightweight, a wall thickness of the top plate 11 is generally not designed to be too thick, so the structural strength of the top plate 11 is relatively limited. In order to enhance the connection strength between the first buffer member 41 and the top plate 11, in some embodiments, as shown in FIG. 2, a reinforcing plate 6 may be disposed at a position of the top plate 11 corresponding to the first buffer member 41, and the reinforcing plate 6 may be made of a metal material, so that the reinforcing plate 6 has high structural strength. Here, the shape of the reinforcing plate 6 in the present disclosure may be adaptively designed according to needs. In addition, compared with arranging the reinforcing plate 6 on the entire top plate 11, arranging the reinforcing plate 6 at the position of the top plate 11 corresponding to the first buffer member 41 can provide a reliable connection for the first buffer member 41, while reducing the occupation of the space inside the cabinet 1 and having a lighter weight.
In other embodiments, referring to FIG. 3 to FIG. 10, the vibration damping structure 4 may include a support beam 42 connected with the cabinet 1. The support beam 42 may play a role in supporting the second drum 3, and the vibration of the second drum 3 may be transmitted to the support beam 42, thereby sharing the vibration of the second drum 3. Further, referring to FIG. 3, FIG. 5, FIG. 7 and FIG. 10, the vibration damping structure 4 may further include a second buffer member 43 disposed between the second drum 3 and the support beam 42. The second buffer member 43 may adopt a structure similar to that of the first buffer member 41, that is, the second buffer member 43 may also be an elastic structure such as a suspension spring, or a damping structure such as a damper. In this embodiment, the second drum 3 can obtain a more reliable vibration damping effect by disposing the support beam 42 and the second buffer member 43 respectively. In addition, the support beam 42 can also play a role in supporting and fixing the second drum 3, and related devices of the second drum 3, such as an air duct, may be fixed by means of the support beam 42.
In other embodiments, as shown in FIG. 3, the vibration damping structure 4 may include a support beam 42, and the support beam 42 may be directly connected with a top wall surface of the top plate 11 of the cabinet 1. In this way, the top plate may provide an installation foundation for the support beam 42 and absorb the vibration transmitted by the second drum 3.
In some embodiments of the present disclosure, referring to FIG. 1 and FIG. 2, the laundry treatment apparatus further includes a balancing member 5. The balancing member 5 may be connected between a lower part of the second drum 3 and the cabinet 1, and/or the balancing member 5 may be connected between a side part of the second drum 3 and the cabinet 1, and/or the balancing member 5 may be connected between the first drum 2 and the second drum 3. It should be noted that the balancing member 5 here is different from the aforementioned vibration damping structure 4 and plays a role in fixing and balancing the second drum 3. For example, the balancing member 5 may also be configured to have a certain elasticity, such as being configured as an elastic bracket. When the vibration of the second drum 3 is too large, it can share part of the pressure of the vibration damping structure 4, so that the pressure does not all fall on the vibration damping structure 4, and the service life of the vibration damping structure 4 is prolonged. Taking a case where the vibration damping structure 4 is disposed only above the second drum 3 as an example, the balancing member 5 is disposed above the second drum 3 to keep the second drum 3 balanced in an up-down direction when it vibrates; in this case, the balancing member 5 may be, for example, a hook disposed below the second drum 3. The balancing members 5 disposed on the left and right sides of the second drum 3 are used to keep the second drum 3 balanced in a left-right direction when it vibrates; in this case, the balancing member 5 may be, for example, an elastic baffle. The balancing member 5 may be disposed at any suitable position within the cabinet 1 according to actual needs, such as avoiding the components within the cabinet 1.
In the embodiment including the support beam 42, the support beam 42 may be configured to have different structures according to actual needs. In some embodiments, referring to FIG. 7 to FIG. 9, the support beam 42 is only connected with one wall surface of the cabinet. That is, the support beam 42 does not extend to other wall surfaces, but is in a suspended state. The wall surfaces here include the front wall surface, the rear wall surface, the left wall surface and the right wall surface of the cabinet 1, as well as the top wall surface of the top plate 11 and the bottom wall surface of the bottom plate of the cabinet 1. In addition, the support beam 42 may be configured as an independent component or a part of the wall surface. On the one hand, this structure of the support beam 42 can avoid the first drum 2 or other components by adjusting a length of its own extension; on the other hand, compared with the structure of a through beam having two ends connected with the cabinet 1, it can also reduce the amount of materials used and meet the lightweight design requirement of the laundry treatment apparatus.
In some embodiments, under the embodiment where the support beam 42 is only connected with one wall surface of the cabinet, referring to FIG. 7, the support beam 42 may be configured as a slat shape as shown in FIG. 1, where one end thereof is connected with the wall surface of the cabinet 1 and the other end thereof is a cantilever end; alternatively, as shown in FIG. 12, the support beam 42 may also be configured as a U-shaped plate, having two ends connected with the wall surface of the cabinet 1, and a portion connecting the two ends forms a cantilever end; or, as shown in FIG. 11, the support beam 42 may include a U-shaped beam segment that is opened at the lower end, and the U-shaped beam segment may be arranged right above the second drum 3 and connected with the second drum 3 through the second buffer member 43. The U-shaped beam segment can be bent according to the devices that need to be avoided, and has higher flexibility.
In other embodiments, referring to FIG. 3, FIG. 4 and FIG. 10, the support beam 42 is configured to be simultaneously connected with at least two wall surfaces of the cabinet 1. That is, different from the above-mentioned embodiment, in the other embodiments, the support beam 42 is configured as a through beam connected with at least two wall surfaces of the cabinet 1. Referring to FIG. 3, FIG. 4 and FIG. 10, the two ends of the support beam 42 may respectively extend to the left wall surface and the right wall surface of the cabinet 1; alternatively, referring to FIG. 5 and FIG. 6, the two ends of the support beam 42 may respectively extend to the front wall surface and the rear wall surface of the cabinet 1. Since the two ends of this through beam are connected with the wall surfaces of the cabinet 1, it has better installation stability, and thus can provide more reliable support for the second drum 3.
In still other embodiments, the support beam 42 may also be configured in a cross shape, a T-shape or an L-shape. The cross-shaped support beam 42 may be simultaneously connected with four wall surfaces; the T-shaped support beam 42 may be simultaneously connected with the left and right wall surfaces and the front wall surface, or simultaneously connected with the left and right wall surfaces and the rear wall surface, or simultaneously connected with the front and rear wall surfaces and the left wall surface, or simultaneously connected with the front and rear wall surfaces and the right wall surface; the L-shaped support beam 42 may be simultaneously connected with the left wall surface and the front wall surface, or simultaneously connected with the left wall surface and the rear wall surface, or simultaneously connected with the right wall surface and the front wall surface, or simultaneously connected with the right wall surface and the rear wall surface, or simultaneously connected with the top wall surface of the top plate 11 and one of the front, rear, left and right wall surfaces, or simultaneously connected with the bottom wall surface of the bottom plate and one of the front, rear, left and right wall surfaces. In these embodiments, the support beam 42 may be integrally formed, or may be formed by splicing a plurality of beam bodies. In a scheme of splicing the plurality of beam bodies, there is a splicing overlapped area, and since strength of the overlapped area is higher, the overlapped area may be located below the second drum 3. The front, rear, left and right directions here refer to the front, rear, left and right directions when the panel of the laundry treatment apparatus faces the user in a normal use state.
In other embodiments, referring to FIG. 10, the two ends of the support beam 42 may respectively extend to the left wall surface and the right wall surface of the cabinet 1, and the second drums 3 may be respectively suspended on the left and right sides of the support beam 42. In this way, the laundry treatment apparatus of the present disclosure may be configured as a three-drum washing machine. Such suspending the two second drums 3 on the left and right sides of the support beam 42 is beneficial to balancing the stress of the support beam 42 and improving the support effect of the support beam 42 on each second drum 3.
In other embodiments, referring to FIG. 5 and FIG. 10, the support beam 42 may be spaced apart from the top plate 11 of the cabinet 1. Here, the wall surface of the cabinet 1 can be used to support the support beam 42 to space the support beam 42 apart from the top plate 11, so as to prevent the vibration of the second drum 3 from being transmitted to the top plate 11 through the support beam 42.
In some embodiments of the present disclosure, referring to FIG. 4 and FIG. 6, the support beam 42 may include a first beam segment 421 and a second beam segment 422, where the second beam segment 422 is connected with the second drum 3, and a width of the second beam segment 422 is larger than that of the first beam segment 421. That is, the support beam 42 is configured such that its own width tapers from a side close to the second drum 3 of the cabinet 1 to a side away from the second drum 3. In this way, since the support beam 42 has a wider width at the position corresponding to the second drum 3, it can provide a reliable support and vibration damping effect; while the first beam segment 421 may not be used for supporting or suspending components, so it can be configured to be narrower than the second beam segment 422, thus meeting the lightweight design of the laundry treatment apparatus.
In addition, referring to FIG. 8 and FIG. 9, the support beam 42 may include a plurality of first beam bodies 424 arranged at intervals, or the support beam 42 may include one second beam body 425. Specifically, in the embodiment shown in FIG. 9, the support beam 42 adopts one wider beam body, while in the embodiment shown in FIG. 8, the support beam 42 adopts a plurality of narrower beam bodies arranged in parallel, for example, two relatively narrower beam bodies may be adopted. When a plurality of narrower beam bodies are adopted, it is equivalent to performing material reduction design on one wider beam body, which is beneficial to meeting the lightweight design of the laundry treatment apparatus while satisfying the vibration damping and support effects. In these embodiments, although the illustration is given by taking the cantilever beam as an example, it should be understood that it can be applied to all the above-introduced schemes with the support beam 42, which will not be repeated here.
In some embodiments of the present disclosure, referring to FIG. 13, at least part of the vibration damping structure 4 may be configured as the top plate 11 of the cabinet 1, and the second drum 3 is connected to the top plate 11. That is, the top plate 11 of the cabinet 1 may be configured as a part of the vibration damping structure 4. Thus, the top plate 11 may support the second drum 3, and the vibration of the second drum 3 may be transmitted to the top plate 11, so that the top plate 11 may share the vibration of the second drum 3, and the vibration damping structure 4 can realize the vibration damping of the second drum 3.
In other embodiments of the present disclosure, referring to FIG. 14 and FIG. 15, a reinforcing structure 7 may be disposed on the top plate 11 of the cabinet 1, at least part of the vibration damping structure 4 may be configured as the reinforcing structure 7, and the second drum 3 is connected to the reinforcing structure 7. In this way, by using the reinforcing structure 7 which is a part of the vibration damping structure 4, the second drum 3 may be supported, and the vibration of the second drum 3 may be transmitted to the reinforcing structure 7 and then to the top plate 11. At this time, the reinforcing structure 7 may share the vibration of the second drum 3, and the vibration damping structure 4 can realize the vibration damping of the second drum 3. In addition, the connection between the second drum 3 and the top plate 11 may be omitted by disposing the reinforcing structure 7.
In some embodiments, the reinforcing structure 7 may be integrally formed with the top plate 11. In this way, the connection between the reinforcing structure 7 and the top plate 11 may be omitted, and the number of components of the laundry treatment apparatus can be reduced. Certainly, in other embodiments, the reinforcing structure 7 may also be detachably connected with the top plate 11; for example, the reinforcing structure 7 may be detachably connected with the top plate 11 through fasteners, or the reinforcing structure 7 and the top plate 11 may be clamped together. Specifically, one of the reinforcing structure 7 and the top plate 11 may be provided with a buckle, and the other may be provided with a clamping slot, and the clamping connection between the reinforcing structure 7 and the top plate 11 can be realized through the clamping of the buckle and the clamping slot. Certainly, in other embodiments, the reinforcing structure 7 may also be fixedly connected with the top plate 11. For example, the reinforcing structure 7 may be welded to the top plate 11, or the reinforcing structure 7 may also be embedded in the top plate 11, which is not limited in the present disclosure.
In some embodiments, referring to FIG. 14 and FIG. 15, the reinforcing structure 7 may be configured in any suitable manner; for example, the reinforcing structure 7 may include a projection 71, the projection 71 protrudes toward the bottom plate 11 of the cabinet 1, and the second drum 3 is connected to the projection 71. In this way, by using the protrusion of the projection 71 toward the bottom plate, the connection between the projection 71 and the second drum 3 can be realized in the embodiment where the projection 71 is arranged close to the second drum 3 without changing the position of the second drum 3 as much as possible.
In some embodiments, referring to FIG. 14, the projection 71 may be configured as a rectangular platform, and the second drum 3 is at least connected to the bottom surface of the projection 71. In this way, the projection 71 of the rectangular platform can simplify the structure of the reinforcing structure 7.
In other embodiments, referring to FIG. 15, the projection 71 may be configured as an arc-shaped platform, and the second drum 3 is connected with the arc-shaped platform in a shape-fitting manner. In this way, the contact area between the projection 71 and the second drum 3 can be increased, thereby improving the vibration damping effect of the projection 71 on the second drum 3.
